Patented Mar. 17, 1931 UNITED STATES PATENT OFFICE JOHN S. STOKES, OF HUNTINGDON VALLEY,

PENNSYLVANIA, ASSIGNOR TO STOKES PENNSYLVANIA METHOD OF ASSEMBLING, WRAPPING, AND STAYING COMPOSITE BOXES Application filed February 15, 1926. Serial No. 88,231.

My invention comprehends the utilization of an individual wrapper, sheet, label, or equivalent, hereinafter generically termed a "wrapper, and particularly a tabbed or reinforced wrapper, for holding a plurality of individual components, sections or elements of suitable material in the form of a box, box top, carton, container structure, or equivalent, hereinafter generically termed a box.

In accordance with my invention, a box is formed or constructed by assembling in suitable relation a plurality of separate individual box-forming components and retaining such components in box-forming position by a previously prepared individual wrapper.

Further in accordance with my invention, there is applied to an individual wrapper a coat of adhesive, as glue, or equivaent, and, before material drying or setting of the adhesive, the coated side of the wrapper is first engaged with a box-forming component destined to form one or more sides of the completed box and thereafter with one or more box-forming components entirely individual and separate from the first-mentioned boxforming component, to the end that all of the box-forming components are maintained in box-forming position by the coated Wrapper; and more particularlv, prior to engagement of the individual coated wrapper with a box-forming component, there are applied to the coated side thereof a plurality of reinforcing elements 01' tabs to whose exposed surfaces there is then applied adhesive, and, before material drying or setting of the adhesive coatings, the individual tabbed wrapper is suitably applied to the box-forming components with the tabs or reinforcing elements overlying the box-corners.

My invention resides in a method of applying an individual wrapper, and more particularly a tabbed or reinforced individual wrapper, to a plurality of individual boxforming components and to a method of ma nipulating and assembling simultaneously the individual box-forming components and wrapper to form a completed box.

My invention resides in a method of the character hereinafter described and claimed.

For an understanding of my method and for an illustration of my product or article, reference is to be had to the accompanying drawing in which:

Fig. 1 is a plan view illustrative of boxlfJorming components utilizable for forming a Fig. 2 is a plan view of a coated tabbed wrapper.

Fig. 3 is a plan view of a coated tabbed wrapper with a box-forming component adhering thereto.

Fig. l is an elevational view of the upper form block of a wrapping machine, showing box-forming components carried at opposite ends thereof Fig. 5 is a perspective view of a tabbed wrapper in registering relation with a boxforming component, the form block structure of a wrapping machine being indicated in dotted lines.

Fig. 6 is a perspective view generally the same as Fig. 5, but showing another position of the form block structure after the wrapper and box-forming component have been engaged one with the other.

Figs. 7 to 11, inclusive, represent, respectively, in perspective the successive stages of a box-forming and box-wrapping operation.

Heretofore, boxes have been constructed from one-piece blanks having cut-out corners. The excess material thus excluded cannot ordinarily be salvaged and, therefore, is an item of expense in the production of boxes ordinarily yielding no return.

In accordance with my invention, the old method of forming a blank from a one-piece blank is discarded and, as a substitute, a plurality of separate and distinct box-formin components are associated with an mdlvidua adhesive-coated wrapper in such manner that the wrapper maintains such components in box-forming position. As a result, in practicing my invention, I effect a decided saving in material as well as labor, particularly the cost of the box blank corner-cutting operation.

An individual coated wrapper of any suitable shape or configuration may be 'utilized for securing the various box-forming components in the desired box-forming position.

The wrapper may be either tabbed or untabbed. If tabbed, the wrapper may be of the general character illustrated in my prior Letters Patent No. 845,205, involving the gluing of reinforcing strips or tabs to an uncoated wrapper, by any suitable mechanism, such, for example, as that oi the character disclosed in prior Letters Patent to Reif snyder et al., No. 1,060,026, or to Nitsch et al., No. 1,451,782. With a wrapper of this character, the adhesive holding the tabs to the wrapper is allowed to dry or set, and the tabbed wrappers are stored, as in stacks, until later used in the wrapping operation when each tabbed blank and the exposed faces of the tabs are coated with adhesive, as in an automatic gluing or adhesive-applying machine, and thereupon applied to the boxforming components, as in a wrapping machine of the character disclosed in Letters Patent to Smith No. 691,329 or 778,805 or to Federwitz et 9.1., 1,541,036. Or, and preferably, the both operations of applying reinforcing elements or tabs to the wapper, and of coating the box-engaging faces of the wrapper and tabs with adhesive, are performed just prior to the application thereof of the box-forming components and before drying or setting of the adhesive coatings as disclosed in my U. S. Patent No. 1,599,500, granted September 14, 1926.

Referring to Fig. 1, there are illustrated three boxforming components, sectionsor elements of suitable sha eorconfi uration and of suitable material, as hox-boar paper, pasteboard, cardboard, or other material, destined to form a generally rectangular box after proper manipulation and assembly. As shown, there is provided a main box-forming component A, preferably scored or creased as indicated by the two parallel lines a, the scored portions constituting opposite boundaries of a generally rectangular section b forming, upon completion of the box, one face thereof, as the bottom. Lying respectively outwardly of the scored portions of box-forming component A, aforesaid, are the substantially duplicate sections 0 and 01 forming, upon completion of the box, oppu site faces thereof, as the two sides.

The substantially duplicate box-forming components, sections or elements B and B1 shown in Fig. 1 as lying at each end of boxforming component A, during the forming and wrapping operation hereinafter described, are associated with and connected or secured to said component A in angular relation with their edges in registering relation for forming, upon completion of the box, opposite faces thereof, as the two ends.

In Fig. 2, I have illustrated an individual corner cut wrapper WV, consisting of a single sheet of paper or equivalent material, of suitable configuration, for example, as disclosed in a prior patent to myself and another, No.

1,265,273, May 7, 1918, or as shown in my copending application Serial No. 89,127 filed February 18, 1926, consisting of a composite wrapper comprising a plurality of component elements secured to each other. As herein shown, wrapper 1V comprises a bottom section at and the front and rear wall sections 6 and The front wall section e comprises the corner lap sections 61 and 62, while the rear wall section f comprises the corner lap sections f1 and f2. Bottom section cl comprises the end wall sections (21 and d2.

\Vrapper W is first coated on one face thereof in selected regions or over the entire facial area with glue or equivalent adhesive, the application of the adhesive being made while the wrapper is in a stack thereof or, and preferably, after removal from the stack.

Thereafter, one or more tabs T, of any suitable material as paper of any suitable form and size, is or are applied to that portion of the coated wrapper destined to come into engagement with the edges, corners or other portions of the box for reinforcing or strengthening the completed box, as hereinafter described. In the example illustrated, both sides of the tabs T, when applied to wrapper WV, are free of adhesive, the adhe sive coating upon said wrapper serving to secure the tabs. It will be understood, however, that the wrapper-engaging faces of the tab T may be coated with adhesive before application to the coated wrapper W, though it is preferred, and will ordinarily suffice, that the wrapper-engaging faces of the tabs be uncoated when applied to the coated wrapper.

Tabs T may be severed, as needed, from a suitable ribbon or roll, or may be first formed and piled in stacks and withdrawn as and when required, all as disclosed in my said U. S. Patent No. 1,599,500.

After the tabs have been so applied to the prcviousl coated wrapper W, the boxengaging sur aces of the tabs are coated with adhesive, yielding, as indicated in Fig. 2, a coated wrapper W with adhering coated tabs T.

The tabbed Wrapper has now been pro pared for application to the box-forming components illustrated in Fig. 1, and such application is preferably made promptly, while the coated wrapper W and its coated tabs T are soft and pliable, and before the adhesive coatings upon the wrapper and tabs have dried, hardened or set.

Initially, engagement may be effected between box-forming component A and the individual wrapper \V in such manner that bottom section b and side sections 0 and c1 of said component A, respectively, engage and adhere to bottom section (Z and front and rear wall sections e and f of said wrapper W. As indicated in Fig. 3, the length of boxforming component A, or the distance along a line a thereof, is such that the component extends from the apexes of the notches on one side of the wrapper to the apexes of the notches on the other side thereof. Further, the width of component A, or the distance along a line at right angles to the lines a, thereof, is such that free portions of the front and rear wall sections e and f of wrapper \V are exposed, Fig. 3. Such exposed sections are tucked around the front and rear sides of the box, as hereinafter described.

lVhen wrapper N is reinforced with tabs T as indicated in Fig. 2 and box-forming component A is engaged therewith in the manner illustrated in Fig. 3, it will be found that the opposite edges of said component at right angles to the lines a, thereof, divide tabs T into substantially equal portions, those nearest the center of the wrapper lying between component A and the Wrapper while the other portions lie exteriorly of component A and are not engaged thereby.

At the next stage in the operation, a form block or equivalent structure may be so placed as to overlie section b of the component A comprised in the composite structure indicated in Fig. 3. The base of this form block corresponds in size with section 7, and is of a height corresponding generally with the distance across either section a or section 01 of box-forming component A, along a line drawn at right angles to the lines (2, thereof.

Assuming that the structure shown in Fig. 3 is in a horizontal position with box-forming component A, overlying wrapper W, sections 6, and f, of said component, the portions of Wrapper W adhering thereto and the outwardly positioned tabs T are bent upwardly into vertical positions, the scored or creased construction of element A readily permitting this action.

At the next stage in the assembling operation, box-forming components B and B1 are located in vertical positions and suitably held at each end of, and in engagement with, the form block. Fig. 7.

Thereafter, the now vertical corner lap sections el and f1 of wrapper W are folded inwardly into engagement with box-forming component B1 while corner lap sections 02 and f2 of said wrapper are likewise folded into engagement with box-forming component B, Fig. 8.

End wall section rll of wrapper W is now folded upwardly into engagement with boxforming component B1 and the adhering corner lap sections already folded into engagement therewith. Similarly, end Wall section (Z2 of said wrapper is folded upwardly into engagement with box-forming component B and its adhering corner lap sections, Fig. 9.

Finally, the portions of the wrapper protruding above the upper edges of the now vertical box-forming walls are folded downwardly and into adhering engagement with the interior surfaces of said vertical walls to form the completed box illustrated in Fig. 11.

It will be observed that the various reinforcing tabs T respectively overlie the various dihedral corners of the box and adhere to all the box faces meeting in any corner. As a result, the box corners are reinforced and the set-in box-forming components, ends or elements B and B1 are tirmly and securely bound to the main box-forming component, section or element A.

All the foregoing operations may be performed manually. Preferably, however, they will be performed by automatic mechanism. For example, the individual wrappers \V, when in a stack, may be operated upon in an automatic adhesive applying machine, such, for example, as disclosed in Nitsch et al. application Serial No. 69,249, or in the adhesive-applying unit G of Federwitz and Bailey application Serial No. 40,769. The individual coated wrappers, as \V, may then be tabbed by any suitable mechanism, in cluding such, for example, as of the character disclosed in the aforesaid Letters Patent No. 1,060,026, or 1,451,782, or, and preferably, during pauses in their travel from the gluing machine G to the wrapping machine \V, in a system such as disclosed in the aforesaid Fcderwitz et al. application Serial No. 40,769, as by suitable mechanism associated with the conveyor or feeding unit C of that system. Accordingly, individual tabbed wrappers V are fed in succession in proper relation between the form block structure of a wrapping machine as shown in broken lines in Fig. 5 and comprising the upper and lower form blocks F and F1 operated as well understood in suitable timed relation by the usual rods f4 and The wrapping machine aforesaid may be of any suitable charactcr as, for example, of the same general type disclosed in the aforesaid Smith Patents 691,329 and 778.80."), or the aforesaid Federwitz et al. Patent 1,541,036: or. and preferably, in a wrapping machine V of the aforesaid Federwitz ct al. application, Serial No. 40.769, to which the tabbed Wrappers are fed in succession by the conveyor unit 0.

The usual guide rods 74 comprised in the wrapping machine support rods or members m4 extending laterally from said guide rods. Carried respectively by members 1224 are the holding fingers or clips (*4. As well understood in the art, guide rods 4 move relative to rod f4 whereby, when form block F is in its upper region of travel. holding fingers cl are positioned entirely thereabovc. However, as the form block pursues its downward course, the ends of the holding fingers more downwardly into the position illustrated in Fig. 4.

Preferably boxforming components B and B1 are piled in previously prepared horizontally-disposed stacks S and S1, Fig. 4, suitably arranged at the same ends of the form mediately thereafter, holding fingers cl \Vhile form block F is in its upper region of travel aforesaid, individual box-forming components are suitably removed from the stacks S and S1 and transferred into engagement with the ends of the form block. 11nmediately thereafter, holding fingers a l move into the position indicated in Fig. 4, whereby said components are positively retained in engagement with the ends of form block F.

Box-forming components A may be individually fed or transferred in succession between the upper and lower form blocks of the wrapping machine in any suitable manner, preferably, however, in a system such as disclosed in the aforesaid Federwitz et al. application, Serial No. 40,769, as by the boxadvancing structure or rods therein disclosed for delivering individual box-structures beneath the upper form block.

Accordingly, in the Wrapping machine, an individual tabbed wrapper W and a boxforming component A come into proper register with each other in proper relation to the descending form block F to which the boxforming components B and B1 are secured during its descending movement, Fig. 5.

In Fig. 6, a stage of the operation is illustrated wherein the upper form block F has effected engagement of wrapper W and boxforming component A and the composite structure has been moved into engagement with the lower form block F1.

Figs. 7 to 11, inclusive, illustrate succeeding stages in the box-assembling and wrapping operation, Fig. 11, showing the finished article, a wrapped box 132. By the operations described, either manual or as performed by the automatic mechanism of the wrapping machine, the wrapper flaps are applied to the box-forming components in suitable sequence, the tabs T being at suitable times applied to and worked around the box corners.

Although the foregoing description is limited to the formation of a box from a specified number of box-forming components, sections or elements, it shall be understood that my invention comprehends the utilization of a greater or smaller number of such components. Further, it shall be understood that my invention also comprehcnds the manipulation and assembly of a desired number of box-forming components in other ways specifically different from the corresponding disclosure of this application.

Likewise, it shall be understood that types of individual wrappers may be utilized differing from the wrapper WV herein disclosed,

and that in the region or regions where the reinforcing tab or tabs is or are applied may be varied as desired to effect proper reinforcing or strengthening in the desired regions of the completed composite box structure.

It shall also be understood that my invention is not to be restricted to the utilization of a wrapper that is tabbed, strengthened or otherwise reinforced, since at times and under certain conditions, it may be desirable to utilize a plain wrapper wherein all strengthening or reinforcing structure or tabs is omitted. Plain wrappers of such character may be fed in succession to a wrapping machine, as aforesaid, in any desired manner, for example, as described above with respect to the delivery of tabbed or reinforced wrappers.

It shall also be understood that the tabbed wrapper may be applied to the box-forming components after the adhesive securing the tabs to the wrapper has hardened or set although, as indicated above, it is desirable that application of the wrapper to the boxforming components be effected before the adhesive coating on the wrapper has materially hardened or set.

When utilizing a composite wrapper, for example, as illustrated and described in my aforesaid co-pending application, Serial No. 89,127, filed February 18, 1926, it is preferable that the application of the wrap er to the box-forming components be efiecte prior to material hardening or setting of the adhesive with which the wrapper components are coated.

In the wrapping operation heat may be applied, as disclosed in my co-pending application Serial No. 71,178, filed November 24, 1925, to set or to hasten settin or drying of the adhesive which holds the ta s, when used, to the wrapper and of the adhesive on the box-engaging faces of the wrapper and tabs, when used.

The preferred operation is as described, namely, that of utilizing the individual wrapper, and the tabs, when used, as the sole reinforcing or retaining structure for the boxforming components. It shall be understood. however, that the box-forming components may be first assembled and maintained in box-forming position by suitable structure. as by webs overlying the various corners, and that thereafter the individual wrapper, or the wrapper and the adhering tabs, may be applied in any suitable manner.

Inasmuch as a box top is substantially similar to that part of the entire box commonly utilized as the receptacle, it shall be understood, in the appended claims, that the expression box bottom is descriptive either of the box top or the bottom of the receptacle.
